The crisp smell of cut grass, the hum of a well-tuned engine, and the satisfying feeling of a perfectly manicured lawn – all these elements contribute to the joy of lawn mowing. However, even the most reliable lawn mower can falter when its recoil spring, the unsung hero of starting, begins to weaken. This critical component, responsible for the powerful spring-loaded action that pulls the starter rope, can lose its tension over time, making starting your mower a frustrating tug-of-war.
This guide will walk you through the process of installing a new recoil spring, ensuring your lawn mower starts with ease and returns to its former glory. We’ll cover everything from identifying the right spring to troubleshooting common issues, providing you with the knowledge and confidence to tackle this common maintenance task.
The Role of the Recoil Spring: A Spring in Your Step
The recoil spring is a vital part of the starter assembly. When you pull the starter rope, the spring stores energy, then releases it with a powerful push, turning the crankshaft and starting the engine. Over time, the spring can lose its tension, becoming less effective and making starting your mower more difficult.
Identifying the Right Recoil Spring for Your Lawn Mower
Before embarking on your spring replacement journey, you must find the perfect fit for your mower. Here’s a step-by-step guide:
Step 1: Understanding Your Mower Model
The first step is to identify your lawn mower’s model number. This information is typically located on a sticker on the mower’s frame, beneath the engine cover, or on the owner’s manual. Once you have the model number, you’ll be able to locate the correct replacement spring.
Step 2: Locating the Recoil Spring
The recoil spring is usually located in the starter assembly, typically housed beneath the starter handle. It’s a coiled spring attached to a spring hook, and it may be covered by a protective shroud.
Step 3: Comparing Springs
If you’re replacing the spring yourself, take the old spring to your local hardware store, garden center, or online retailer. Be sure to note the spring’s length, diameter, and any other specific features to ensure a perfect match.
Tools of the Trade: What You’ll Need
To ensure a smooth and efficient spring installation, you’ll need the following tools:
- Screwdriver: A Phillips head screwdriver will be necessary for removing and replacing screws on the starter assembly.
- Pliers: Pliers will come in handy for adjusting and securing the spring hook.
- Wrench: A wrench may be required to loosen or tighten nuts that hold the starter assembly in place.

Reconnect the spark plug wire to the spark plug.
Step 7: Testing the Spring
Test the spring by pulling the starter rope. It should feel smooth and consistent, with a good, strong pull. If the spring feels weak or uneven, check the installation and ensure the spring is properly seated.
Troubleshooting Common Issues: When Things Don’t Go as Planned
Sometimes, even with careful attention to detail, you might encounter issues during installation or after. Here are some common problems and solutions:
- Spring not properly seated: Double-check that the spring is securely attached to the starter assembly and that it’s not caught on any other components.
- Spring tension too loose or too tight: The spring tension might need to be adjusted slightly by moving the spring hook on the starter assembly. Consult your owner’s manual for specific instructions for your model.
- Spring breaking: If the spring breaks during installation, it’s likely a sign of a worn-out or faulty replacement spring. Purchase a new spring from a reputable source to ensure quality.
